Struct DeviceFvmState 

pub struct DeviceFvmState<T: FvmScalar, B: AcceleratorBackend> { /* private fields */ }

Persistent scalar fields used by the two-kernel conservative FVM path.

Implementations

impl<T: FvmScalar, B: AcceleratorBackend> DeviceFvmState<T, B>

pub fn upload( backend: &B, plan: &DeviceFvmPlan<B>, cell_values: &[T], face_mass_flux: &[T], boundary_values: &[T], ) -> Result<Self, AcceleratorError>

Upload persistent field data and allocate flux/residual workspaces.

pub fn upload_components( backend: &B, plan: &DeviceFvmPlan<B>, components: usize, cell_values: &[T], face_mass_flux: &[T], boundary_values: &[T], ) -> Result<Self, AcceleratorError>

Upload component-major state and allocate persistent workspaces.

pub fn upload_sources( &mut self, backend: &B, face_source: &[T], cell_source: &[T], ) -> Result<(), AcceleratorError>

Refresh explicit component-major face and cell source arrays.

pub fn upload_boundary_overrides( &mut self, backend: &B, values: &[T], ) -> Result<(), AcceleratorError>

Enable explicit per-component Dirichlet overrides for every boundary face.

Operator evaluations normally use the values packed in the boundary policy. This method is the explicit opt-in for component-dependent Dirichlet data.

pub fn clear_boundary_overrides( &mut self, backend: &B, ) -> Result<(), AcceleratorError>

Disable all explicit per-component Dirichlet overrides.

pub fn components(&self) -> usize

Number of component-major fields in this state.

pub fn cell_values(&self) -> &B::Buffer<T>

Read-only resident cell values.

pub fn face_mass_flux(&self) -> &B::Buffer<T>

Read-only resident face mass fluxes.

pub fn residual(&self) -> &B::Buffer<T>

Read-only resident residual values.

pub fn gradient_x(&self) -> &B::Buffer<T>

Read-only resident x-gradient values.

pub fn upload_cell_values( &mut self, backend: &B, values: &[T], ) -> Result<(), AcceleratorError>

Refresh all component-major cell values.

pub fn upload_face_mass_flux( &mut self, backend: &B, values: &[T], ) -> Result<(), AcceleratorError>

Refresh the shared face mass-flux field.

pub fn download_residual(&self, backend: &B) -> Result<Vec<T>, AcceleratorError>

Download the gathered residual vector.
